St Kilda 61–83 Western Bulldogs in AFL Round 15 at Marvel Stadium. Here's how the result stacked up against the model's call, with the win-probability story and where the value landed.

Sixty-eight to 64. That's the intercept count, Western Bulldogs' way, and it's the number that explains how a team beaten in almost every other category on the stat sheet still walked out of Marvel Stadium with an 83-61 win over St Kilda.

Because on paper this should have been St Kilda's night. More disposals, 424 to 384. More contested ball, 144 to 128. More entries inside 50, 59 to 43, and more hit-outs, 41 to 31, courtesy of a ruck division that had the better of things all evening. St Kilda did almost everything you'd want a side to do to win a footy match. They just didn't win it.

The scoreboard tells you where it went wrong. St Kilda were within two points at quarter time, 22 to 20, and still very much in the contest. Then the Bulldogs put together the term that decided it, outscoring St Kilda badly through the middle two quarters to lead 58-44 at the last change. From there it was about closing it out, and the Bulldogs did that without fuss, adding 25 to St Kilda's 17 in the final term.

That's where the intercepts bite. St Kilda kept pumping the ball forward, 59 inside 50s worth of pressure, but the Bulldogs kept taking it back off them, 68 times to 64. Marks inside 50 tell the same story in miniature: Western Bulldogs 11, St Kilda 9. All that St Kilda territory and it wasn't translating into clean use once it got there, evidenced by St Kilda's disposal efficiency sitting at 72.6% against the Bulldogs' 73.4%. Small gap, but enough over four quarters.

None of this should come as a total shock given how the two sides rated coming in. Western Bulldogs held the edge in midfield strength, 1196 to 1130, and in the forward ratings, 1170 to 1109, and those are exactly the areas that decide who profits from repeat entries and who gets picked off. St Kilda's one clear advantage was defence, rated 1125 to the Bulldogs' 1051, but that unit was up against it for three quarters running before finally tightening up in the last.

Form lines pointed to a tight one. St Kilda had won two of their last five, the Bulldogs three, and the Bulldogs came in conceding fewer points on average, 89.8 to St Kilda's 97.6. Alphr's model had Western Bulldogs favourites at 51%, expecting them by 10.6 points in a game totalling around 170. They won by 22 in a match that finished on 144, a good deal tighter on the scoreboard total than tipped but a fair bit more one-sided in the margin. The model still landed the right side, the right margin band and the under, going 3 from 4 on the night.

St Kilda will look at that stat sheet and wonder how they lost by more than three goals. The answer's in the turnovers. Volume without control only gets you so far.

**Model Report Card**

Western Bulldogs defied the model's 51% prediction for St Kilda, a notable result. The predicted margin of 10.6 was reasonable against the actual 22-point result. The game's 144 points came in 26 points lower than the predicted 170. The model went 3/4 on this match. Western Bulldogs covered the 0.5-point line. The 1-39 margin band call landed. The under 184.5 total call was correct.

### Match Preview (pre-match read)

Line ball between St Kilda and Western Bulldogs. The model can't split them, landing on St Kilda at 51%. The ratings say otherwise: Western Bulldogs sit 38 ELO points clear, 1504 to 1466, so the model is backing St Kilda against the ratings gap. Form leans Western Bulldogs' way: 3 from their last 5, against 2 for St Kilda.

On paper Western Bulldogs shade it, ahead on 4 of 7 factors including ELO Difference, Midfield ELO and Recent Win Rate. The model still sides with St Kilda, which says Defensive ELO and Scoring Form carry the most weight. The margin model has Western Bulldogs by 10.6, with the two sides combining for about 170. Coin-flip on the win, so the value is where this one gets settled.
